Currently show_config() has a problem when user and system config files
have the same config variables i.e.:
# cat ~/.perfconfig
[top]
children = false
When $(sysconfdir) is /usr/local/etc
# cat /usr/local/etc/perfconfig
[top]
children = true
Before:
# perf config --user --list
top.children=false
# perf config --system --list
top.children=true
# perf config --list
top.children=true
top.children=false
Because perf_config() can call show_config() each the config file (user
and system). Fix it.
After:
# perf config --user --list
top.children=false
# perf config --system --list
top.children=true
# perf config --list
top.children=false
